I've intermittent fasted for the past year. I have lost 100 pounds. Almost limitless energy. No need for anti depressants. Healthiest and happiest I've ever been. I'm 45 years old and in the shape of my life. Massive mental clarity. I have even subsided some of my health problems. I have reversed the aging process. Fountain of youth here folks.

***** I have a tendency to iron deficiency so I had to eat after five days of fast and I also read that it is better to try and get vitamins and minerals every day with fruits and vegs.

[@tomcotter4299]

+Sandra Carli I don't know if it's coincidental or not, but I did notice in the most recent semester of classes that I was very alert, and very sharp. It was as if witty or insightful responses were always right on the tip of my tongue, waiting to be used. I also noticed a sense of enhanced intuition as you noted, as if I could anticipate a professors question or statement, and formulate a response well in advance. And I wonder if this is due to the fact that I was unintentionally subjecting myself to a form of quasi-ketogenic diet. Certain circumstances basically led my diet to be as such: Wake up 7:30-8, go get a large peanut butter infused coffee--cream only, no added sugar--, and go directly to classes until roughly 2pm. Which is far different than my typical morning routine which is to wake up and immediately consume a substantial (although relatively well balanced) meal.My schedule this semester will allow me to do the quasi-Keto diet three days a week, and give me time to do my typical routine the other two. I look forward to examining the side-by-side comparison! :)

[@morelius]

Hi. I'm a Buddhist priest. Thank you for this video. I can personally say that intermittent fasting has always been part of our human nature. Have you ever noticed that when you got the flu, you barely want to eat? That's your body screaming you to leave it alone so it can heal! So why is it that you force yourself into having a bowl of chili or soup? Fasting heals you. Make you feel great and the mind is sharp and clear. Most of the Buddhist monastic community worldwide have only 2 small meals a day and this has been going on for thousands of years. So try skipping breakfast. That's all you need to lose weight, lower your carbon imprint and feel great.

[@tabloharuxx693]

Hi, I see you have left your comment here from 2 months ago. Can you share with me how you fast? such as the duration of fasting etc. Also do you usually drink water while fasting?

[@morelius]

Tabloharuxx Hi! I fast daily by skipping dinner and once or twice a month I do a 24 hours fasting. It's really simple, actually. I drink water and a little coffee or tea. The first couple of days are hard, but once you start feeling great, you fall in love with fasting. Other benefit is that you get less hungry on your food days, so you lose weight nice and steady. Try it!

[@premghinde5560]

I skip breakfast now everyday. I have a hearty salad with some form of protein for lunch and then whatever I like for dinner. I started this for weight loss reasons but I am now so productive during the day and much less easily distracted.

Very interesting point about trying to force feed your body when sick. I do believe in force feeding it water when you are sick because having those stomach convulsions because you have nothing to throw up isn't fun at all, but next time I'll try not eating when I'm not hungry.

[@someone5444]

Tabloharuxx eat only one meal a day and have 2-3 apple or banana or any such fruits and drink milk eat little bit of nuts, I don't have breakfast in lunch I eat 20-30 grams of nuts (almonds and walnuts mostly) and one apple or banana, I have dinner at 8:30 pm I am indian so I have vegetarian meal cottages cheese, roti, lentil soup, little salad, butter milk etc. I don't drink or smoke Once a week I have my cheat day,I don't like sugary things I love burgers etc. I am topper of my class always a straight A student 😀

Great video. Thank you sir :). I’ve done the 16/8 fasting and lost 40 pounds in like 4 months, but that didn’t work great for me because I could still not control my hunger, I just couldn’t wait to finish my diet so I can eat bread, cake again. I’m just hungry all the time. A year later I’ve decided to increase my fasting period.For 1.5 months now, I’ve been fasting 36 hours 3 days a week (I don’t eat Monday, Wednesday and Friday). And I feel amazing. My hunger is way way way way down, I can actually manager those urges to eat all the time, I have much more energy, and I feel like my thinking is clear . The hunger still comes in waves, but if I can keep busy for 20-30 min, it just goes away(and is very mild), and I still cook everyday for my husband and son. The only problem now, is that I’m bored, because all that time I used to think about food, now suddenly I have to fill it up with something else... and I lost another 15 pounds... but my greatest achievement of all, is NOT BEING HUNGRY ALL THE TIME

Fasting is incredible, the benefits you get from it are borderline super-powers. They've been shoving the lie that we need 3 meals a day down our throats (literally) for years. Too much food makes you fat, lethargic, toxic, depressed, dishonest, poor and I can go on and on. The hardest thing about fasting is the fear and the withdrawal from addiction to food that you will inevitably go through at first.

I have fasted intermittently since Jan. 2016. I've noticed a big difference in my thinking ability. Faster recuperation from a hangover. Better sleep. Better mood. More energy. And I have lost 40 lbs. I started out fasting Monday, Wednesday, Friday. And eating one big meal, meaning anything I wanted and as much as I wanted on the other days. Also having wine most days! I have kept the weight off, today is Nov. 28, 2016. 8 months. I can tell my brain functions better. I now have one meal or less a day eating whatever I want including ice cream etc. I am so grateful for your research Mark Mattson!

[@AnaBlackened]

I have borderline personality disorder, and I've been doing a low-carb diet and intermittent fasting, has worked wonderfully for me, I been sleeping better (6-8 hours which is alot for a border) , I have less mood swings, and although I know that this will not solve my life 100% at least has helped me alot, i decided to start this diet after i read that it was good for epileptics and schizophrenics , i was taking same medication, anticonvulsants and antipsychotics, so i told myself "why not?" and i don´t regret :D Sorry about my english

[@ATMfromNJ]

+Lana de Ville Be sure to not go TOO low carb. If you dip too low, you will eventually mess with your endocrine system (i.e. disturbed sleep, decreased metabolism, etc). So do include healthy carbs in your diet regularly (e.g. sweet potatoes, beans, etc). No need to take it to the extremity that is ketosis. Best of luck.

[@AnaBlackened]

AT M thanks alot for your advice! i totally gonna start eating more of that!

[@Kavetrol]

+Lana de Ville Best approach with carbs is to have them as a treat at the end of the meal, not as a snack or bulk of your food. Also you could try eating some sardines a few times a week. Vitamin D helps a lot with the mood swings but it may take a few months to have an effect.(all advice from personal experience)

[@Mhapple]

+Lana de Ville Gluten free may also help also. Read the book "Wheat Belly" .. this with fasting will be great for you. For instance, during WWII there were food shortages and a lot of disease actually declined. When life went back to normal and it even got better after the war that illnesses came back all the more.

[@AnaBlackened]

TED talks are amazing. Information flowing straight from research labs to the public, kind of like intersection of science and public thirst for knowledge. Thanks TED for being the platform you are. This talk is an eye opener. Although I have been aware of the benefits of fasting to some extent, this talk drives home the point convincingly. I wish there were ads/campaigns on TV and internet urging people to adopt healthy lifestyle habits like intermittent fasting and exercising and meditation to balance against the blatant campaigns for consumerism all the time.

For starters try: 18:6 Intermittent fasting.....(don't eat after 6pm or before 12pm next day = 18 hour fast) Your eat window is from 12pm-6pm (6 hours) .... periodically do a 24 hr fast (lunch one day no eating until lunch next day (24 hour fast). Your HGH will increase, you will lose weight and your blood glucose, cholesterol, triglyceride levels will improve.

A small percentage of the population will deny themselves food in a culture of excess. I recently did a 6 day fast. It was empowering and freeing. I'm a 10 year vegan and often skip eating for a day or so and have for years. I recommend people ease into a fast with a clean vegan diet for a couple weeks before fasting to be most successful. The first 3 days are the most difficult after is bliss. (BTW, I'm no kid . . . 60 years old).

[@jeffrey322]

I too have fasted for 6 days; for those who are curious, it's quite a high in that all of your senses become heightened and you reach a state of clarity. You are not hungry after 6 days (is true) and by day 5 or 6, you no longer want to "dirty yourself" by eating again (altho you will by breaking the fast properly). I followed a book by Paavo Airola.

[@hebince44]

Great to see another vegan do the fasting :) Why don't you continue with IF, it is less hard and can be maintained for years every day. It has long term benefits.

[@joeschmo5699]

I eat a moderately high fat vegetarian diet (about 40% fat). I've started dabbling in intermittent fasting. I love it. But I haven't gone multiple days or anything. The furthest I've gone is miss breakfast and lunch and then workout with weights and running. I think I'm pretty "fat adapted" because that was easy. Frighteningly easy. I still wasn't hungry. I just ate something because I thought it would be a good idea after working out. But I felt I could have gone for days. It's pretty strange.

Thank you for the work that you do Mark.

[@CristianKirk]

Great talk. I discovered fasting pretty much on my own when I was a kid. Always had a problem with the 4-meals-a-day program... I would think, "what's the point of eating when you're not hungry or waiting to whatever hour to eat if you're hungry now?" People is just too absorved in the psycohological structures of the dominant consumerist culture. As Mattson said in the talk, at first it is painful and difficult, because it's hard to break the daily 4-meals program, but once you get used to it, you feel it just makes sense.

It does take practice but I convinced that this is the way forward to reduce food related diseases.

I’ve just stumbled upon fasting and I’m fascinated by it. I’m always very in tune with my moods and my energy levels and I’m very aware of how I feel. I always eat healthy and exercise everyday and have a relatively physical job in which I’m on my feet for 8 hours, I tried fasting expecting to ‘crash’ about the same times in which I usually would when my body starts running out of energy but my how I was wrong, I feel consistently better throughout the day and don’t feel the same emotional pulls towards food. Try it!

Wow! This was 7 years ago. I wish I'd known this before. I just started fasting (Keto-IF-extended fast,four mouths ago). I lost 40 pounds. No exercise. I feel great. The last time I was at this weight was decades ago. If you want an updated take on Keto/Low carb and fasting, watch Sten Ekberg's videos. You need 3-5 days for autophagy. According to Ekberg, you also produce HGH. 3 days of water fasting is now easy to do for me. I am trying to do a 4-5 days fast once a month. The rest of the days, I do IF. Btw, i also minimized carbs and removed processed food from my meal plan. It also saves you a lot of money.
